It is wrong for a man to say that he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty.
Science is organized common sense where many a beautiful theory was killed by an ugly fact.
Interpretation
What this quote means
Science refines our intuitive understanding by systematically testing ideas against reality, often challenging our beautiful theories with harsh facts.
In this quote, Thomas Huxley emphasizes that while science is grounded in rationality and common sense, it is also a rigorous discipline that demands evidence. The quote highlights the tension between attractive theories, which may seem appealing and plausible, and the often harsh reality of factual evidence that can debunk or contradict those theories. It serves as a reminder that in the realm of scientific inquiry, empirical data takes precedence over mere speculation or aesthetic appeal.

Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists-whether through design or stupidity, I do not know-as admitting that the fossil record includes no transitional forms. Transitional forms are generally lacking at the species level, but they are abundant between larger groups.
The weight of evidence for an extraordinary claim must be proportioned to its strangeness.
One of the reasons for its success is that science has a built-in, error-correcting machinery at its very heart. Some may consider this an overbroad characterization, but to me every time we exercise self-criticism, every time we test our ideas against the outside world, we are doing science. When we are self-indulgent and uncritical, when we confuse hopes and facts, we slide into pseudoscience and superstition.
If I could remember the names of all these particles, I'd be a botanist.
The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers.
Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.
